Hospitexte: towards a document-based hypertextual electronic medical record.

The patient record is a repository for knowledge about a patient. Work in Artificial Intelligence and knowledge representation has evidenced the intrinsic difficulty of formalizing knowledge for computer processing. It is therefore not a surprise that most attempts at computerizing the patient record have only had a limited degree of success or applicability. We claim that this is due to the fact that medicine is an empirical domain, and thus fundamentally resists formalization. Therefore, the only way medical knowledge can be fully expressed is through natural languages which is indeed what clinicians actually use. We proposed and designed an electronic medical record which adheres to this hypothesis and where structured documents play a prominent role.

A patient education program.

Everyday language used by health care professionals in gastroenterology is often unfamiliar to patients, regardless of their level of education. Consequently, the best efforts to explain diagnoses to patients can result in confusion and anxiety instead of understanding. A patient education program was designed in an attempt to correct this problem. This article describes how the patient education program was developed and implemented.

Language training for generalization.

This paper presents a classroom-based language intervention program for preschool children with language delays or deficits. A major goal of the program is to ensure that children acquire missing skills through daily speech therapy and that they actively generalize these skills from therapy times to other classroom activities. This paper presents data collected with two children during daily speech therapy sessions and daily play activities. Instances in which the children generalized new language acquired in therapy to play activities will be discussed as well as instances in which the children failed to generalize new language. In addition, the influence of peer and teacher language usage on children's language production will be discussed. Finally, recommendations to enhance generalization of language skills within and across school settings will be presented.

A hardware-independent data acquisition package incorporating a simulation driver and simulation description language.

Device drivers for commercial data acquisition boards (DASH-16, DT2801) and a device driver for a virtual data acquisition board have been developed and incorporated in a single package for a multiple station anesthesia research laboratory. The package provides a compiler for a simulation description language which is used to program the virtual board. The package, written in C for the IBM PC, was designed to be easily extended with additional drivers. Applications using the package can control all supported devices without the programmer having to learn the details of the hardware.

Maternal speech to normal and Down's syndrome children matched for mean length of utterance.

The study was designed to provide data on the maternal linguistic environments of normal and Down's syndrome children at three levels of language development, as assessed by children's mean length of utterances (MLU). The three MLU levels were 1.00--1.50, 1.75--2.25, and 2.50--3.00, respectively. The subjects were 21 Down's syndrome children and their natural mothers and 21 normal children and their natural mothers. Normal children ranged in chronological age from 20 to 32 months and Down's syndrome children from 3 to 12 years. A one-hour verbal interaction between mother and child was tape recorded at home in a free-play situation. Maternal speech was analyzed using 20 measures related to its output-numerical, lexical, syntactical, semantic-structural, semantic-pragmatic, and language-teaching aspects. Additionally, eight measures of children's speech related to the output-numerical, lexical, syntactical semantic-structural aspects, and to imitativeness of maternal speech were computed as a means of testing the validity of the MLU-matching that forms a basis for this study. Except for the Type-token ratio, which favored Down's syndrome children, normal and Down's syndrome children were not found to differ. In contrast, there were numerous differences between the children in the different aspects of speech considered according to language level. None of the comparisons made of mother's speech to normal and to Down's syndrome children led to differences for any of the three children's language levels studied. It appeared that the maternal linguistic environments of language-learning Down's syndrome and normal children of corresponding MLU were similar in most respects. In contrast, there were numerous differences in mother's speech according to the language level of the children addressed. This confirmed that the expressive language level of the children is a far more powerful factor in influencing maternal speech than whether they are normal or Down's syndrome children. The implications of these findings were related to the delay-difference question in the language development of Down's syndrome children and to various interpretations of the effects of maternal linguistic input for language development and for intervention programs of language enhancement in the Down's syndrome child.

Receptive and expressive language problems occurring in combination with a seizure disorder: a case report.

The purpose of this case report is to present an example of a child with receptive and expressive language problems occurring in combination with a seizure disorder. For a period of 3 years the seizure disorder appeared to be controlled by medication and the child made substantial improvement in a language remediation program. A sudden disruption of decoding abilities was the only behavioral indication that the treatment program needed to be reassessed. Descriptions of the child's behaviors, subsequent neurological evaluation, and goals of the language habilitation program are presented.

Genetic programming over context-free languages with linear constraints for the knapsack problem: first results.

In this paper, we introduce genetic programming over context-free languages with linear constraints for combinatorial optimization, apply this method to several variants of the multidimensional knapsack problem, and discuss its performance relative to Michalewicz's genetic algorithm with penalty functions. With respect to Michalewicz's approach, we demonstrate that genetic programming over context-free languages with linear constraints improves convergence. A final result is that genetic programming over context-free languages with linear constraints is ideally suited to modeling complementarities between items in a knapsack problem: The more complementarities in the problem, the stronger the performance in comparison to its competitors.

Aphasic patients in a rehabilitation program: scheduling speech and language services.

Eleven 10-item tests from the Porch Index of Communicative Ability (PICA), were administered to 14 aphasic adults participating in a rehabilitation program. Tests were given once in the morning and once in the afternoon. Results indicate that overall communicative functioning was significantly higher for morning assessments, although some individual patients did better in the afternoon. The primary implication of these results is the importance of consistency in scheduling patient contacts when measuring the effects of treatments rendered. Considerations in determining optimum schedules and aiding individual patients in compensating for reduced efficiency due to time of day are discussed.

The effects of a community-based literacy program on young children's language and conceptual development.

Effects of a community-based literacy program on 1-, 2-, and 3-year-old children's language and conceptual development were assessed. University students were trained to teach Head Start parents effective methods for reading to their children. Families were randomly assigned to receive 18, 3, or 0 instructional visits. Results indicated that parents in the 18-instructional-visit program increased their participation in appropriate literacy behaviors such as reading to their children, teaching concepts to their children, and using the library, more than parents in the 0-instructional-visit groups. Children in the 18-instructional-visit program showed greater gains in language and conceptual development than children in the 0-instructional-visit group. Few differences were found between children in the 3-visit and 0-instructional-visit groups. Thus, only a high-intensity community-based intervention designed to train parents was effective in increasing emergent literacy in low-income ethnic children.

Soft-testing of industrial control systems programmed in IEC 1131-3 languages.

This paper presents a technique and the means for testing PLC-based control software outside the actual plant environment with the purpose of increasing the confidence level on the compliance of the software to functional and temporal requirements. The need to obtain a high confidence level on the correct software operation arises from the fact that in most of the cases it is quite dangerous and expensive to test unproved PLC operation by linking it with the actual facilities that it is going to control. The proposed technique relies on a combined simulation of the controlled plant and the PLC system and an analysis of the plant responses. The PLC system simulation imitates the way software is executed on a PLC that is programmed in the languages of the IEC1131-3 standard. It is based on the programming model of the IEC standard and analytical formulae for estimating the program runtime. The simulation of the plant is based on a discrete convolution model that is solved at the same rate with the rate determined by the control algorithms. A tool realizing these concepts has been developed and its use in testing the control software of three critical outputs of a distillation column is demonstrated.

Language plus for international graduate students in nursing.

PURPOSE: To provide information about an English-language support program that focuses on the needs of international graduate nursing students. The growing presence of these students coincides with the increasing numbers of universities committed to world health. Crucial social and language competence affect the success and progress of international students in graduate nursing programs. DESIGN: Reviewed literature was 1980 to 1998, in nursing and applied linguistic research including second-language acquisition, phonology, discourse analysis, and language pragmatics to identify social and language phenomena. FINDINGS: Investigators suggest essential elements such as conventions of academic writing, reading comprehension, vocabulary, and pronunciation skills be included in the supportive Language Plus program. CONCLUSIONS: Ongoing development of the Language Plus program can promote collaboration between nurses and linguists and increase the success of international graduate nursing students.

Effects of modeling and corrected practice on generative language learning of preschool children.

A simultaneous treatments design was used to compare the effects of modeling and corrected practice on generative language acquisition of six preschool children. New syntactic forms used to describe agent-action and agent-action-object stimuli were taught concurrently. All six children learned both new syntactic forms. However, generative language learning was accomplished more efficiently with corrected practice, irrespective of the number of words or the linguistic complexity of utterance forms. When modeling was not effective initially, instructing two children to start talking like the model resulted in rapid observational learning. It is suggested that descriptive researchers may have prematurely discounted the possible role of corrected practice in the enhancement of language learning. This analog study indicates that corrected practice should provide a more efficient approach for establishing generalized syntactic responding, at least initially, in language intervention programs.

A method for vocabulary development and visualization based on medical language processing and XML.

A comprehensive controlled clinical vocabulary is critical to the effectiveness of many automated clinical systems. Vocabulary development and maintenance is an important aspect of a vocabulary, and should be linked to terms physicians actually use. This paper presents a method to help vocabulary builders capture, visualize, and analyze both compositional and quantitative information related to terms physicians use. The method includes several components: an MLP system, a corpus of relevant reports and a visualization tool based on XML and JAVA.
